Typechecking functions accepting classes (as opposed to instances) about typedecorator HOT 2 OPEN

Thanks for the suggestion @mejedi . It certainly looks like a useful use-case. I'm trying to think of a good way to represent this check (as opposed to the instance chek) in the signature, any ideas?

It also might be possible to cover this use-case if #5 is implemented, so you could do arbitrary checks, eg:

def subclass(base):
    return lambda cls: isinstance(cls, type) and issubclass(cls, base)


@params(cls=subclass(MyClass))
def myfunc(cls):
    ...

Thoughts?

Thoughts?

The library is already capable of expressing complex assertions in function signatures, I mean Nullable and Union. Extending this with a Class is probably not too ugly.
